Yes, absolutely freaking yes.
You love Jackman and then turn around and complain about Thornton? Jackman who follows Kane across the ice the punch in the back of the head, subtly butt-end the second the ref is looking the other way, etc.? The same guy who said, and I quote, when the Blackhawks complained about how the Blues played "Sorry we hurt their feelings"
I can only presume you would not want Pronger on the team either.

Flatly speaking, if the Blues were able to somehow land Thornton for a good price (which I doubt, it would require losing one of our two main centers, other serious pieces, etc.) the Blues would finally have an imposing #1 center which they have been lacking for a very, very long time. Army would be absolutely stupid to not inquire were San Jose to make it known that Jumbo was available. I would take Thornton on my team any day of the week and frankly anyone disagreeing because of farcical issues needs to consider watching the first round from this year again.

I don't think they are farcical issues whatsoever. I'm sure it would be pretty awkward for Perron to play on the same team with him after being put out for 13 months with a dirty hit by Thornton. Jackman doesn't carry near the baggage that Thornton does and he has also been on our team for eight seasons. Your presumptions are right, Pronger has had a lot of good seasons with the Blues in the past and in the NHL all together but with his injuries, cost, and age I don't see many more NHL games from him let alone seasons.
